' OIL-CUP.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ALBERT C. GRUNWALD,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Oil-Cups, of which the following is a specification.

This invention relates particularly to oil cups adapted to be applied to bearings where it is not convenient to employ forced feed. The primary object is to provide an oil cup which will serve to gradually feed the oil to thebearing, and which is adapted to effectively exclude dust and grit.- A further object is to provide a simple and inexpensive construction, well adapted to the purose.

p The invention is illustrated in its preferred embodiment in the accompanying drawing, in which- Figure 1 represents an elevational view, partly in section, of the improved oil'cup; Fig. 2 a plan view of the same; and Fig. 3 a plan view of a wick cup employed.

In the construction illustrated, A represents an oil cup having a reduced, threaded nipple A at one end and equipped at the other end with a cap A and B represents a wick, or fibrous material, which extends through the nipple and has its upper portion confined in an inverted cup B ,which fits in thelower portion of the cup A.

The cup A may be formed by a drawing operation from a disk of steel, the metal being drawn into tubular form, reduced at the lower portion to form the nipple A, and perforated to provide a passage for the wick. Above the nipple A, the cup is enlarged somewhat, as indicated at 1, thus providing a chamber which receives the inverted cup B and the upper portion of the wick. The

member B may be stamped from a thin disk of sheet metal, thus providing the disk portion 2 and a flange 2 The disk portion 2 is provided with a central perforation which is formed by striking the metal upwardly and perforating it, thus providlng a perforate embossment or flange 2 The upper portion of the wick is preferably compacted within the chamber provided by the member B, and flange 2 of the member B is forced into the contracted cylindrical wall 1 of the cup. The oil, in order to reach the wick,

must pass through the perforation encircled by the flange 2", so that any sediment which may be carried by the oil will be deposited in the lower portion of the cup above the member B, but cannot pass to the wick; thus clogging of the wick is avoided.

The cap A of V the oil cup is shown equipped with a segmental closure 3 which is secured to the cap by means of a central rivet or pivot 4. The top wall of the cap is provided with a perforation 5 through which oil may be introduced, and provided with stops 6 which limit the swing of the closure about the pivot 4. However, any other suitable detail of construction may be em loyed at the upper portion of the oil cup.

he improved oil cup is adapted for use in connection with the bearings of stationary engines, the bearings for springs of automobiles, and in various other situations. The improved device is exceedingly simple in construction, may be cheaply manufactured, and is thoroughly" effective for its purpose. size to properly lubricate an ordinary hear- The cup may be of convenient ing for a period of several weeks, without the necessity of re-filling the cup in the meantime.

What I regard as new and desire to secure by Letters Patent is:

1. A device of the character set forth comprising a cup provided with a nipple for attachment to a bearing, and a wick device comprising fibrous material and an inverted cup in which the upper portion of said fibrous material is confined, said inverted cup being forced into the base portion of the oil cup above said nipple and having a perforation in its wall through which oil may ass.

2. A device of the character set forth comprising a cup. provided with a nipple for attachment to'a bearing, and a wick device comprising fibrous material and an inverted cup in which the upper portion of said fibrous material is confined, said inverted cup being forced into the base portion of the oil cup above said nipple and having a perforation surrounded by a flange, through which oil may pass.

3. A device of the character set forth comprising an oil cup provided at its base with a reduced portion and below said reduced portion With a reduced, threaded nipple portion, an inverted cup confined in said firstmentioned reduced portion and having a perforation therethrough, and Wick material 10 in said nipple and having its upper portion confined in said inverted cup.

ALBERT C. GRUNWALD.
